Assembly: System (in system.dll)

Public Class UploadDataCompletedEventArgs
	Inherits AsyncCompletedEventArgs
Dim instance As UploadDataCompletedEventArgs

public class UploadDataCompletedEventArgs extends AsyncCompletedEventArgs
public class UploadDataCompletedEventArgs extends AsyncCompletedEventArgs
Not applicable.

Instances of this class are passed to the UploadDataCompletedEventHandler.

The following code example demonstrates asynchronously uploading data.

Public Shared Sub UploadDataInBackground2(ByVal address As String)

    Dim client As WebClient = New WebClient()
    Dim text As String = "Time = 12:00am temperature = 50"
    Dim data() As Byte = System.Text.Encoding.UTF8.GetBytes(text)
    Dim method As String = "POST"

    AddHandler client.UploadDataCompleted, AddressOf UploadDataCallback2
    Dim uri as Uri = New Uri(address)
                client.UploadDataAsync(uri, method, data)
End Sub

The following method is called when the upload completes.

Private Shared Sub UploadDataCallback2(ByVal sender As Object, ByVal e As UploadDataCompletedEventArgs)

    Dim data() As Byte = CType(e.Result, Byte())
    Dim reply As String = System.Text.Encoding.UTF8.GetString(data)

End Sub
